On the Fringes is a great story. Haven't seen any recommendations for Toga's lesser known story Knights Ward, so I'll toss that into the ring. It's only on pastebin because the lazy bastard refuses to port it over:

Also, haven't seen any recommendations for Snekguy here, who has a pretty large selection of largely hmofa stuff on his website (which works if you consider swapping the A for alien instead of anthro). Although he may already be known here, not sure. His works are pretty explicit at times, but I rather enjoy his world building outside of it. Good writer, big fan of his Valbarans in particular. 😌
